ABSTRACT

The present invention relates to a composition containing an inducer of SIRT1 (silent mating type information regulation 2 homolog) expression for preventing or treating sepsis or septic shock. The inducer of SIRT1 expression can remarkably reduce the mortality caused by sepsis or septic shock by reducing pro-inflammatory cytokines and increasing anti-inflammatory cytokines. Therefore, the inducer of SIRT1 expression is useful for preventing or treating sepsis or septic shock.

TECHNICAL

The present invention relates to a composition containing an inducer of SIRT1 (silent mating type information regulation 2 homolog) expression for preventing or treating a sepsis or septic shock.

BACKGROUND ART

Bacterial infections and other strong stimuli may initiate an immune reaction which may cause a systemic inflammation or a systemic inflammatory response system (SIRS). A serious SIRS causes serious fever, hypotoxemia, trachypnea, tachycardia, endothelium inflammation, myocardial dysfunction, mental disorder, blood vessel collapse, and eventually a multiple organ failure syndrome (MODS) which accompanies an organ injury, e.g., an acute respiratory distress syndrome, coagulation disorder, heart failure, renal failure, shock and/or coma.

A sepsis is defined as a situation in which an infection has been confirmed or is doubted along with systemic inflammatory response. A sever sepsis is defined as a case an which a sepsis is accompanied by an organ dysfunction (low blood pressure, hypoxia, oliguria, metabolic acidosis, thrombocytopenia, consciousness disorder). A septic shock is defined as a case in which blood pressure is not normalized even if infusion therapy is used or medicine for enhancing blood pressure is used. The sepsis may progress to a severe sepsis and finally a clinical step of a septic shock. The clinical sepsis is defined in a broad sense as a state in which the invasion by the microorganism agent is related with the clinical symbols of the infection. The clinical symbols of the sepsis are (1) Body temperature >38° C. or <36° C.; (2) Heart rate >90 times per minute; (3) Respiratory rate >20 times per minute or PaCO₂<32 mmHg; (4) The number of white corpuscles >12000/cu mm, <4,000/cu mm or >10% immature (band) form; (5) organ dysfunction or high blood pressure, but the present invention is not limited to these examples.

If an infection occurs, the macrophage of the infection region is activated so as to secrete TNF-α and IL-1, thereby the amount of discharge of the plasma protein into the organs increases, the movement of phagocytes and lymphocytes to the organs increases, and the attachment of the blood platelets on the walls of the blood vessels increases. In this way, the local blood vessels are closed, and the pathogenic organisms are concentrated on the infected region. Particularly, in the sepsis, the systemic infection occurs, and the serious blood vessel closure induced by TNF-α is accompanied. Further, the systemic discharge of TNF-α causes the loss of the volume of the blood plasma due to the blood vessel enlargement and the increase of the permeability of the blood vessel, thereby causing a shock. In the septic shock, TNF-α further stimulates blood coagulation, thereby causing generation of blood clots and mass consumption of blood coagulation protein in small blood vessels. Since the blood coagulation ability of a patient is lost, important organs such as kidney, liver, heart, and lung are damaged by the dysfunction of the normal vessels. It has been reported that the mortalities of the severe sepsis and the septic shock reach 25 to 30% and 40 to 70%, respectively.

In many cases of the sepsis, the pathogenic organism. is E. coli, but gram negative bacteria such as Klebsiella-Enterobact-Serratia group and Pseudomonas may also cause such a state. Gram-positive microorganisms such as Staphlococcus, systemic viruses and Fungus may also cause the sepsis.

Urogenital vessel, gastrointestinal vessel and respiratory tract are most commonly infected regions which cause the sepsis. In addition, other sepsis-related infection regions are a or burn region, a pelvic infection region and a catheter infection region within a vein, etc.

The sepsis mostly frequently occurs in a hospitalized patient suffering from a basal disease or symptom sensitive to the invasion of the hematocele, or a burn, wound or surgical patient. Factors of making a person sensitive to the invasion of the hematocele are a weakened immune system, for example, an immune system of an infant or an elderly person, and a symbol, or disease which increases a local sensitivity to infection, for example, a weakened circulation, diabetes, uremia and AIDS. Finally, a subject having a tendency of a weakened immune response which may occur due to the existence of various allelic genes of IL-1 gene also has a greater possibility of an outbreak of the sepsis (U.S. Pat. No. 6,251,598).

It is understood that the sepsis is generated as a result of complicated reciprocal action between bacteria causing infection and the immune, inflammation and coagulation system of the host. Both the response level of the host and the features of the bacteria causing infection significantly affect the convalescence of the sepsis. Organ failure observed in the sepsis occurs when the response to the bacteria causing the infection of the host is inappropriate, and if the response is excessively increased, the organ of the host itself may be damaged. Based on this concept, antagonists to TNF-α, IL-1β, IL-6, which are proinflammatory cytokines that perform a leading role in the inflammation response to the host, has been used in an attempt to cure the sepsis, but most of the attempts have failed, and injection of activated protein C and treatment of glucocorticoid are now being used in an attempt to cure the sepsis, but many limits are being indicated. Hence, there is a need for a new treatment for preventing or treating the sepsis and the septic shock.

SIRT1 (silent mating type information regulation 2 homolog; sirtuin 1) is known as an enzyme for regulating the function of the protein by deacetylating the lysine residue of various proteins, which depends on NAD+ (Ageing Res, Vol. 1, pages 313-326, (2002)), and is most similar to Sir2 of the yeast having (NAD+)-dependent class III histone deacetyl activity. In particularly, SIRT1 cuts the acetyl group attached on the transcription factor such as Nuclear factor-kB and p53 (Cancer Res, Vol. 64, pages 7513-7525, (2004); Cell, Vol. 107, pages 149-159, (2001); Trends Endocrinol Metab, Vol. 17, pages 186-191, (2006)). Further, SIRT1 participates in reconfiguration of chromatin related with the inhibition of gene expression, DNA damage response, life extension related with restricted diet, etc. (Chen et al., Science 310, 1641, 2005). That is, SIRT1 reconfigures chromatin through histone deacetylation as in Sir2 of: the yeast, inhibits expression of gene, and induces deacetylation of various transcription factors related with cell growth, stress reaction and internal secretion regulation, etc. as well as histone protein. Further, according to a recent study, there has been a report of a technology which applies the SIRT1 to diabetes, obesity, nervous degenerative diseases or aging related diseases, etc. by increasing the deacetylation of the SIRT1.

Likewise, there is a report on pharmacological effects that the SIRT1 may be applicable to various diseases by increasing the deacetylation activity, but there is no study on pharmacological effects for preventing or treating the sepsis or septic shock. Hence, there is a need for a new treatment for preventing or treating the sepsis or septic shock.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

Hereinafter, exemplary embodiments of the present invention will be described in detail. However, the exemplary embodiments below merely illustrate the present invention, and the present invention is not limited to the embodiments.

Exemplary Embodiment 1 Measuring Amount of SIRT1 Expression After Treatment of LPS and Interferon to Macrophage Originated from Mouse Marrow

Femur and tibia marrow cells of C57BL/6 mouse have been differentiated in culture solution containing M-CSF(10 ng/ml), and then have been used as mouse macrophage. LPS (0, 100, 500, 1000 ng/ml) and interferon beta (0, 100, 200, 500 units/ml) have been injected to the macrophage by concentrations, and the SIRT1 expression amount has been compared by western blot. Further, the SIRT1 protein expression amount when LPS has been injected along with IFN-β blocking antibody has been measured.

The result is shown in FIG. 1.

As illustrated in FIG. 1, when LPS has been injected to the macrophage originated from the mouse marrow by 100 ng/ml, the SIRT protein expression has increased most, and when 500 ng/ml and 1000 ng/ml of LPS has been used, the SIRT1 protein expression has rather decreased. Further, when interferon beta has been used by concentrations, the SIRT1 expression has most significantly increased when 100 units/ml has been used.

Further, the SIRT1 expression increased by LPS decreased again by injecting TFN-β blocking antibody together. Hence, it can be known that the secretion of the SIRT1, which has been increased by LPS, is performed through the interferon beta, and through which the interferon beta induces the expression of SIRT1 (B).

Exemplary Embodiment 2 Influence of Adenovirus-SIRT1 and Interferon Beta on the Amount of Secretion of Pro-Inflammatory and Anti-Inflammatory Cytokines

After infecting the macrophage with the adenovirus-SIRT1 by 10,000 MOI (multiplicity of infection), LPS 100 ng/ml has been injected for 24 hours. Further, LPS 100 ng/ml has been used along with interferon beta 100 units/ml for 24 hours, and then the amount of secretion of pro-inflammatory and anti-inflammatory cytokines of the cell culture medium has been measured by Elisa. The experiment has been performed three times, and the result has been expressed by the average±standard deviation.

The result is shown in FIG. 2.

As shown in FIG. 2, with respect to the amount of the pro-inflammatory cytokines, which has been increased by the LPS treatment, IL-6 has been decreased by 40% and 54%, respectively, and TNF-α has been decreased by 22% and 29%, respectively, by the pre-treatment of adenovirus-SIRT1 and interferon beta. Further, it has been found that MOP-1, which is another pro-inflammatory cytokine, which is increased by the LPS treatment, has, slightly decreases by the adenovirus-SIRT1 and interferon beta. In contrast, it has been found that the amount of the IL-10, which is the anti-inflammatory cytokine, has increased by 2.8 times and 4.7 times, respectively. Hence, it is understood that the treatment by the Interferon beta, which is the cytokine that promotes the expression of SIRT1, may inhibit the excessive inflammatory response by the LPS.

Exemplary Embodiment 3 Analysis of Survival Rate of Mouse After Injecting LPS after Pre-Treatment of SIRT1 or Interferon Beta to Mouse

Adenovirus-LacZ, which is control gene delivery system, and adenovirus-SIRT1, which is the SIRT1 gene delivery system, are injected into the mouse tail vein by 3×10⁸ pfu (plaque forming unit), and LPS 15-20 mg/kg after 48 hours. Then the survival rate of the mouse has been observed for 10 days.

Further, interferon beta 1000 units or the same amount of salt solution per 20 g of the mouse weight is injected into the mouse tail vein, and LPS 15-20 mg/kg has been injected after 30 minutes. Then the survival rate of the mouse has been observed for 10 days.

The result is shown in FIG. 3.

As shown in FIG. 3, When the LPS is injected to the mouse which has been pre-injected with the adenovirus-SIRT1, the survival rate of the mouse after 10 days is and thus the survival rate has been significantly higher than the survival rate 20% of the control group, ane mouse, to which the adenovirus-LacZ has been injected. Further, the survival rate of the mouse, into which the LPS has been injected after the injection of the interferon beta, was 70%, which was significantly higher than the survival rate 30% of the control group, the mouse, into which the salt solution has been injected. The result shows a significant difference even by the Kaplan-Meier survival statistical analysis (p<0.05). Hence, the interferon beta, which is a substance that induces the SIRT1 expression, significantly reduces the mortality of the mouse by the LPS treatment by inhibiting the excessive inflammatory response by LPS.

Exemplary Embodiment 4 Analysis of Survival Rate of Mouse at the Time of Treatment of Adenovirus-Dominant-Negative SIRT1

Adenovirus-Dominant-negative SIRT1, which the gene delivery system for blocking the function of the intrinsic SIRT1, (Adenovirus for inducing mutant protein that has changed histidine no. 355 into tyrosine), is injected into the mouse tail vein by 3×10³ pfu, and after 48 hours, interferon beta 1000 units per 20 g of the mouse weight is injected into the mouse tail vein. After 30 minutes, LPS 15˜20 mg/kg is injected, and the survival rate of the mouse is observed for 10 days.

The result is shown in FIG. 4,

As shown in FIG. 4, in the case in which Adenovirus-Dominant-negative SIRT1 is pre-injected for 48 hours, interferon beta is injected and then LPS is infected into the mouse, the survival rate 50% has been observed after 10 days. This is a result similar to the survival rate 50% of the control group, the mouse into which the salt solution has been injected, and through which the interferon beta, which is the material for inducing the SIRT1 expression, significantly reduces the mortality of the mouse by LPS.

Exemplary Embodiment 5 Analysis of Survival Rate According to SIRT1 and Interferon Beta Treatment in a Mouse Sepsis Model

In a mouse sepsis model, which is induced through cecal ligation and Puncture (CLP) surgery, the following experiment has been performed to check the survival rate changed according to the injection of SIRT1 and interferon beta.

Adenovirus-LacZ or adenovirus-SIRT1 has been injected into the mouse tail vein 3×10⁸ pfu. After 24 hours, the anesthetic is injected into the abdominal cavity, and the sepsis has been caused through CLP. That is, after the center of the abdomen of the mouse is cut, the appendix is exposed to the outside so that the end of the ileocecal valve is ligated by the silk suture, two holes are made using a needle, and then a certain amount of fecal materials are discharged. The appendix as well as fecal materials has been inserted again into the abdomen, then the abdomen has been stitched, and then a physiological salt solution has been injected through a hypodermic injection. After two hours of SLP operation, interferon beta 1000 units or the same amount of salt solution per 20 g of the mouse weight have been injected into the mouse tail vein.

The result is shown in FIG. 5.

As shown in FIG. 5, the sepsis is induced to the mouse into which the adenovirus-SIRT1 has been injected in advance, and the survival rate of the mouse after 10 days was 60%. This is a significantly high survival rate of 0% of the control group, mouse into which the adenovirus-LacZ has been injected in advance.

Further, in the case of the experimental group in which interferon beta has been injected into the sepsis-induced mouse, the survival rate was 76, but in the case of the control group, the mouse into which the salt solution has been injected, the survival rate was 0%. The result shows a significant difference even by Kaplan-Meier survival statistical analysis (p<0.05).

Hence, the interferon beta, which induces the expression of SIRT1, significantly reduces the mortality of the mouse due to the sepsis, and thus may be utilized in preventing or treating the sepsis or septic shock.
